Compressor blade with nozzle

Abstract

A compressor blade having at least one nozzle for ejecting fluid, in particular for ejecting water, is provided. The at least one nozzle is produced as a laminar structure in which, in particular, individual layers such as metal sheets are laid on top of each other, and has differently orientated channel sections of a channel between an inlet and an outlet, wherein the metal sheets have cutouts corresponding to the channel sections. The nozzle geometry makes it possible to prevent the formation of droplets as water exits a compressor blade.

         15 . A compressor blade comprising:
 at least one nozzle for ejecting fluid,   wherein the at least one nozzle is produced as a laminar structure wherein individual layers are laid on top of each other, and   wherein the at least one nozzle has differently orientated channel sections of a channel between an inlet and an outlet, wherein the individual layers have cutouts corresponding to the channel sections.   
     
     
         16 . The compressor blade as claimed in  claim 15 , wherein the channel between the inlet and the outlet is diverted at least once. 
     
     
         17 . The compressor blade as claimed in  claim 15 , wherein the channel between the inlet and the outlet is diverted at least twice. 
     
     
         18 . The compressor blade as claimed in  claim 15 , wherein the channel between the inlet and the outlet is diverted only twice. 
     
     
         19 . The compressor blade as claimed in  claim 15 , wherein the channel between the inlet and the outlet is diverted only once. 
     
     
         20 . The compressor blade as claimed in  claim 15 , wherein the channel is diverted by between 10° and 180°. 
     
     
         21 . The compressor blade as claimed in  claim 15 , wherein the channel is diverted by between 30° and 180°. 
     
     
         22 . The compressor blade as claimed in  claim 15 , wherein the channel is diverted by between 40° and 180°. 
     
     
         23 . The compressor blade as claimed in  claim 15 , wherein the channel is diverted by 90°. 
     
     
         24 . The compressor blade as claimed in  claim 15 , wherein the channel is diverted by between 30° and 70°. 
     
     
         25 . The compressor blade as claimed in  claim 15 , wherein the channel is diverted by 180°. 
     
     
         26 . The compressor blade as claimed in  claim 15 , wherein the channel sections are straight. 
     
     
         27 . The compressor blade as claimed in  claim 15 , wherein the at least one nozzle is provided as a module and is adapted to be inserted into a recess in the compressor blade. 
     
     
         28 . The compressor blade as claimed in  claim 15 , wherein the at least one nozzle comprises an annular or oval arrangement of individual holes. 
     
     
         29 . The compressor blade as claimed in  claim 15 , wherein the at least one nozzle is located within a wall of the compressor blade. 
     
     
         30 . The compressor blade as claimed in  claim 15 , wherein the at least one nozzle is located at the leading edge. 
     
     
         31 . The compressor blade as claimed in  claim 15 , wherein the at least one nozzle is located on the suction face and/or on the pressure face, and is adapted so that the fluid can be fed through the inside of the compressor blade. 
     
     
         32 . The compressor blade as claimed in  claim 15 , wherein the at least one nozzle is located at the leading edge and has a laminar construction, and wherein the material surrounding the at least one nozzle serves as a protective layer against drop impingement erosion. 
     
     
         33 . The compressor blade as claimed in  claim 15 , wherein the individual layers comprise metal sheets. 
     
     
         34 . The compressor blade as claimed in  claim 15 , wherein the at least one nozzle is adapted for ejecting water.
